I did a fresh install again on a new laptop dual boot Windows. I created a partition for linux and used replace partition in the installer. Ive been messing with this trying to figure out the best setup. I want the system when i close the lid to hibernate. Right now it is set to suspend but i see i don’t have swap or hibernate so I’m not sure it’s doing that or just shutting down the display. I left it overnight and battery was dead already. My fstab is them following. ```auto # UUID=F23A-62B4 /boot/efi vfat umask=0077 0 2 UUID=1b3dcd7d-b403-4b62-975f-ebbb0c435982 / ext4 defaults,noatime 0 1 [ricklinux@eos-xfce ~]$ ``` Can i add hibernation after the fact? I need swap file to do that and add info to my fstab? If i do this I’m looking to have the laptop shutdown on hibernation. Is that the way it hibernates? ---

Yes, you need swap{partition,file} to hibernate. Also yes, hibernate actually fully powers off the machine after saving your current state into your swap and setting it to resume from swap. However, I will say, if you have an SSD, hibernation doesn’t get you much. Resuming from hibernate vs. power off/on when system is on an SSD is pretty much the same speed (possible 1-3 seconds slower w/ power on, but very similar). Yes, you can definitely add hibernate after the fact, but there’s a LITTLE more to setting up hibernate from a swapfile than from a swap partition. ---

I just might wipe this off again and install it with hibernation and try it first. Then i will add Windows maybe? Everything seems to work including backlighting. I’ve been experimenting with it. It’s not that I mind Windows it’s the 3rd party crapware and Microsoft’s own crap it installs. I usually take everything out except for Windows 10 and then i add what i want with software. Not Windows store apps. ---

Always install Windows first. Windows does not play well with being installed after other OS’s. ---

swapfile should do the job, as it does not need to change partitions ---

Can you explain how i do this before i end up doing another bare metal install? First make a swap file. Then i have to add stuff to fstab? Plus i have to edit grub? ---

You need a swap partition and `resume=swap_device` kernel parameter to hibernate your system state, although this works a bit differently if encryption is involved. [https://wiki.archlinux.org/index.php/Power\_management/Suspend\_and\_hibernate#Hibernation](https://wiki.archlinux.org/index.php/Power_management/Suspend_and_hibernate#Hibernation) Better to test install your setup on a VM first, rather than bare metal, particularly if not 100% sure of how it all works. I’d recommend not just simpy re-installing, this could be a good learning process for you, just make any mistakes in a VM first. ---

I just made a swap file but it doesn’t show anything in fstab? I guess that is only if you create a swap partition? ```auto [ricklinux@eos-xfce ~]$ free total used free shared buff/cache available Mem: 7554380 1236852 138024 149352 6179504 5865508 Swap: 8191996 0 8191996 [ricklinux@eos-xfce ~]$ ``` Edit: Can i just hibernate to this swap file? Do i need to do anything else? ---

You need to add a swap file entry manually, simply creating a file doesn’t create the fstab entry automatically. ```auto /swapfile none swap defaults 0 0 ``` Take your time. Read the Arch Wiki and understand what you are doing instead of just shooting from from the hip. I wouldn’t recommend using a swap file for hibernation either.

`sudo dd if=/dev/zero of=/swapfile bs=1M count=512 status=progress` 512 must be changed to the size you want (size of your RAM alike) ```auto sudo chmod 600 /swapfile sudo mkswap /swapfile sudo swapon /swapfile ``` Finally, edit the fstab configuration to add an entry for the swap file: `sudo nano /etc/fstab` ```auto /swapfile none swap defaults 0 0 ``` simple as this… to get it working for hibernation/suspend: Add the resume option to grub kernel line to the the UUID of the partition containing your `/swapfile`: ```auto sudo findmnt -no UUID -T /swapfile ``` `sudo nano /etc/default/grub` ```auto # GRUB boot loader configuration GRUB_DEFAULT=0 GRUB_TIMEOUT=5 GRUB_DISTRIBUTOR="EndeavourOS" GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 resume=UUID= **put the uuid here** nowatchdog" ``` regenerating grub.cfg 🖖 ` sudo grub-mkconfig -o /boot/grub/grub.cfg` # note: —\> go to the updated wiki page instead it includes also systemd-boot and more: [https://discovery.endeavouros.com/storage-and-partitions/adding-swap-after-installation/2021/03/](https://discovery.endeavouros.com/storage-and-partitions/adding-swap-after-installation/2021/03/) ---

I actually use fallocate for creating mine, so that I can specify the size in GiB (Gibibytes), so that it’s truly 8. Easier than doing the maths for dd. 😃 `fallocate -l 8Gib /swapfile` ---

Besides the `resume=UUID=` a `resume_offset` value needs also to be added to the boot parameters when hibernating into a swapfile: [https://wiki.archlinux.org/index.php/Power\_management/Suspend\_and\_hibernate#Hibernation](https://wiki.archlinux.org/index.php/Power_management/Suspend_and_hibernate#Hibernation) ---

Eh, it’s not hard. Do it a couple times in a VM and it’ll be simple as anything. Yeah, a few extra commands, but still easy. Just…not worth it to me since I moved to SSD’s. ---

IDK, simply giving a list of commands to blindly copy and paste doesn’t really help Rick understand, which IMHO doesn’t really help him in the long run. I understand EndeavourOS is not Arch, but a certain degree of encouragement to learn should be given for such a simple task. 1 . Create swap partition. 2 . Set resume kernel parameter to swap partition UUID. IDK. [Next page](https://forum.endeavouros.com/t/adding-swap-hibernation-after-install/10831.md?page=2)
